Jonathan Wilson, 21, was the third and final person to be sentenced for the attack on delivery driver Brandon Patterson. Cole Will and Brandon Hamel pleaded guilty and were sentenced to prison earlier this month, but prosecutors called Wilson the ringleader.

Wilson called the assault the worst decision he ever made and said he takes full responsibility, but when asked by the judge why he did it, he couldn't say.

As he did in the plea hearings for the other defendants, Patterson testified about the attack and his injuries.

"Something like this happened, not because I wronged somebody, not because I knew the defendants, but because I was doing my job," he said.

The 30-year-old husband and father said he still suffers physically and mentally from the beating he endured at the hands of Wilson and two others.

"I can't get comfortable ever in social situations," he said. "I'm always looking over my shoulder, wondering what's going to happen, when things are going to happen, and this is not the way I was before."

His father, Ryan Patterson, also gave a statement, calling the attackers' actions evil.

"It's evil, your honor," he said. "It's evil, plain and simple. They cared nothing whatsoever for whatever carnage or victim that they came across."

Prosecutors said Patterson was lured to a vacant building in Somersworth to deliver a pizza. Once inside, he was attacked. The prosecution referred to Wilson as the ringleader and said he hid behind the door and was the first to use violence when Patterson went inside.

"He took the butt end of a sawed-off shotgun and struck this man in the head with it, knocking him out cold," Strafford County Deputy Attorney Alysia Cassotis said.

Patterson was then severely beaten. The state asked that Wilson get the longest sentence of the three, but the judge ended up giving him the same as Hamel, a minimum of 19-and-a-half years. Will was sentenced to at least 12-and-a-half years in prison.

Like Will and Hamel, Wilson apologized to Patterson in court.

"It's been nine months, and I am still struggling with trying to find the words to express my remorse," Wilson said. "Every day, I pray I can take your pain away, change what happened and stop myself from making the worst decision I ever made, but I can't."

Wilson also asked for Patterson's forgiveness. After the hearing, Patterson said that he would be able to forgive him, saying that if he couldn't, what kind of person would he be?

Patterson said he is also satisfied with the sentence and thankful that all the cases are over.
